PIN-POINT CATCH.

To all whom it may concern Be it known that I, ARTHUR LEWIS CAR- NELL,subject of the King of Great Britain and Ireland, residing at Dowlingstreet, Dungog, in the State of New South Wales, Commonwealth ofAustralia, have invented new and useful Improvements in Pin-PointCatches, of which the following is a specification.

The essential feature of the invention consists in pivoting the catch sothat it can oscillate, when required, from side to side. The pivot is,preferably, placed on one side of the catch, so that the catch canoscillate in a horizontal plane. Upon the pivot pin is articulated thecatch which consists of a small cylinder or an oval with a zig-zagcurved slot on the side opposite the pivot. The pin will be introducedinto the catch by turning the latter slightly to one side when the pinwill be introduced into one end of the curved slot and pushed home; the.

catch will automatically straighten itself and be parallel with thelongitudinal axis of the brooch or safety pin. When the brooch or safetypin is to be removed, the catch will be turned on its pivot when thepoint of the pin will slip out of the curved slot in the catch.

In the accompanying drawings ;Figure 1 is a side elevation of the pinand catch fastening. Fig. 2 is a side elevation of the appliance thecatch having been turned to admit the pointed end of the pin into theslot. Fig. 3 is a plan of the same. Fig. 4 is a perspective view of theappliance. Figs. 5, 6 and 7 are, respectively, a plan, front elevationand end elevation of the catch, drawn to a slightly larger scale.

A is the base, which may represent either the front of a brooch or therigid bar of a safety pin; B is the pin secured to the brooch, or therigid bar of a safety pin, at b, in the usual manner. At a point on oneside of the point of the pin B is placed the pivot pin C, and swiveledon the pivot pin 0 is the catch D. If the catch be made in cylindricalform the pivot pin may pass through the center of the cylinder at rightangles to its Specification of Letters Patent.

longitudinal axis, but I have found that a good form for the catch is aflat oval, as shown in the drawings, in Which case the catch will bepivoted at c on the pin C at one side, so that the catch can oscillateto a small extent, in a vertical plane. In the side of the catch Dopposite the pivot pin 0 is a curved slot E of zig-zag form, as isclearly shown in Fig. 6.

When it is desired to fasten the point of the pin in the catch, thelatter will be turned at an angle, as shown in Figs. 2 and 3, the pointof the pin B will be laid in the end of the slot E, the catch D may thenbe turned on its pivot so as to lie parallel with the axis of the pinand the point of the pin will lie securely Within, and be shielded by,the catch. In order that the back of the catch D shall not foul the pin,the back of the pin is cut out in a curve (Z, as may be seen onreferring to Figs. 1, 2, I and 6. If the point 6 be provided With aspring in torsion (which would always be the case with a safety pin),the pin B will rise and assume the position shown in Figs. 1 and 4, butwith a brooch the spring would not be essential as the material that isperforated by the pin would have very much the same effect.

I claim 1. In combination, a pin including a back, a pointed memberpivoted to the back, and a tubular catch member pivoted to the backadjacent to the free pointed end of the pin upon a vertical axis, thesaid catch member being adapted to be moved into parallel relation withrespect to the pin in securing position, or into angularly arrangedreleasingposition, the said member having a tortuous slot in one of itssides opening through its ends and adapted to admit the pin point onlywhen the member is in releasing position.

2. In combination, a pin including a back, a point pivoted to the back,and a tubular catch member pivoted to the back adjacent to the freepointed end of the pin upon a vertical axis, the said catch member beingadapted to be moved into parallel relation with respect to the pin insecuring position, or into angularly arranged releasing position, theseid member having a tortuous slot In testimony whereof I have signed myin one of its sides opening through its ends name to this specificationin the presence of and adapted to admlt the pm point only twosubscrlbing Witnesses.

When the member is in releasing position, ARTHUR LEWIS CARNELL. theopposite side of the catch member being Witnesses:

provided terminally and opposite to the said A. MAssEN;

slot With an auxiliary notch. 'H. C. CAMPBELL.
